DOUBLE-CHECK PIPE CONNECTIONS
During operation, the pressure of the
refrigerant circuit will increase. This may
reveal leaks that were not present during your
initial leak check. Take time during the Test
Run to double-check that all refrigerant pipe
connection points do not have leaks. Refer to
Gas Leak Check section for instructions.

of Checks to Perform have PASSED, do the
following:
a.
Using remote control, return unit to
normal operating temperature.

Using insulation tape, wrap the indoor
refrigerant pipe connections that you
left uncovered during the indoor unit
installation process.
